That is amazing at them speeds. I find my mileage computer is 5% optimistic. I have to hit 31.6 mpg to be actually 30 mpg.Nice work, it is amazing how far these things can go with their huge fuel tanks and some conscious moderation of the throttle.
I had a nice road trip last week, I wasn't keeping track of miles per tank as much as shown MPG, but I recently drove from Atlanta to Minneapolis with cruise control typically set in the 70-75mph range, and had a calculated fuel economy of 30.2mpg for 1061 miles.
My return trip with cruise control mostly set at 80mph, and 27.2mpg for 951 miles
I disagree. My 2013 speedometer is dead on by whatever means you use. It's odometer is only off about 0.5% also.Because if you've been around the scene for more than 10min, you should already know that VAG vehicles always read up to 10% faster than actual GPS speed.... and when I say GPS, I'm talking actual dedicated instruments not some BS phone app or whatever you're using.
